Perspectives on Exporting US Crude?
February 13, 2014 | UPI

A US Senator from Alaska says… “Opening up world markets to U.S. crude oil will lower the global price, which will in turn lower the global prices for petroleum products.”

A US airlines industry VP says… “Exporting U.S. crude makes little sense. [...] If we allow for the export of U.S. crude, we’ll have to import more oil from overseas and subject ourselves, once again, to an increasing degree of price volatility and higher global prices.”

The idea of exporting US crude hits different people different ways. Alaska has a surplus of oil and exporting it to Asia is as easy as delivering it to California. The airlines company owns a refinery in the eastern United States.
